Description
技术领域 technical field
本实用新型涉及烟气监测，特别涉及烟气排放连续监测系统。 The utility model relates to flue gas monitoring, in particular to a continuous monitoring system for flue gas discharge.
背景技术 Background technique
烟气排放连续监测系统，能够对固定污染源排放的颗粒物和气态污染物浓度和排放率进行连续实时的跟踪测定，广泛应用于具有固定污染源(锅炉，工业窑炉，焚烧炉)的工厂。 The flue gas emission continuous monitoring system can continuously and real-time track and measure the concentration and emission rate of particulate matter and gaseous pollutants emitted by fixed pollution sources, and is widely used in factories with fixed pollution sources (boilers, industrial kilns, incinerators).
烟气排放连续监测系统包括依次连接的采样探头、电加热采样管线、预处理处理装置及分析装置，其中预处理装置包括除湿系统和采样泵。工作方式为：采样探头将烟气抽出，再伴热传输(防止烟气冷凝)，传输到烟气分析柜后进行除尘，除湿等处理后经采样泵送入红外分析仪进行分析检测。 The flue gas emission continuous monitoring system includes sequentially connected sampling probes, electric heating sampling pipelines, pretreatment treatment devices and analysis devices, wherein the pretreatment devices include dehumidification systems and sampling pumps. The working method is as follows: the sampling probe draws out the flue gas, and then heats the transmission (to prevent the flue gas from condensing), and then transfers it to the flue gas analysis cabinet for dust removal, dehumidification, etc. After treatment, it is sent to the infrared analyzer for analysis and detection by the sampling pump.
水分是影响红外仪表测量准确性的一个重要因素，现有方式为：在抽气泵前设置有一套冷凝除水装置，通过冷凝除水装置将出口样气露点控制在一定范围。这种方式的不足为：在采样管路发生堵塞或者其它原因导致冷凝除水装置处气压发生变化时，冷凝除水装置将出口样气露点也会随之改变，从而导致红外仪表测量准确性变差。 Moisture is an important factor affecting the measurement accuracy of infrared instruments. The existing method is: a set of condensation dehydration device is installed in front of the air pump, and the dew point of the outlet sample gas is controlled within a certain range through the condensation dehydration device. The disadvantage of this method is: when the sampling pipeline is blocked or other reasons cause the air pressure at the condensing water removal device to change, the dew point of the sample gas at the outlet of the condensing water removal device will also change accordingly, resulting in a change in the measurement accuracy of the infrared instrument. Difference.
流量是影响红外仪表测量准确性的另外一个重要因素，现有方式为：在冷凝器后设置有一套采样回流装置，采样回流装置通常有抽气泵和回流旁路以及调节针阀组成，用以调节烟气采样流量维持在目标值。这种方式的不足为：导致采样回流装置后端的转子流量计虚高，转子流量计显示有正常烟气采样流量，但实际烟气采样流量为零或者只有很少一部分烟气从烟道采集下来的问题。 Flow rate is another important factor affecting the measurement accuracy of infrared instruments. The existing method is: a set of sampling return device is installed after the condenser. The sampling return device usually consists of an air pump, a return bypass and an adjusting needle valve to adjust The flue gas sampling flow is maintained at the target value. The disadvantage of this method is: the rotameter at the back end of the sampling return device is falsely high, and the rotameter shows a normal flue gas sampling flow, but the actual flue gas sampling flow is zero or only a small part of the flue gas is collected from the flue The problem.
